LUBRICATOR.

Specification of Letters Patent.

- Application filed November 2, 1909. Serial No. 525,854.

Patented Jan. 31, 1911.

v To all whom it may concern:

Be it known that I, NATHANAEL L. CHAL- Mm, a citizen ,of the UnitedStates, residmg at Newark, in thecounty of Essex and State of NewJersey, have mvented certain Improvements in .Lubricators', of which thefollowing is a specification.

This invention especially relates to means for lubricating the bearingsof shafts in in which'li a lubricator of my improve and moreparticularly the bearings of trolley cars.

The objects of theinvention are to secure a constant supply of lubricantto the hearing; to ,regu ate the amount of lubricant supplied, and toprevent more than necessary being supplied to the bearing; to thuseconomize lubricant, and effect a saving in expense as well as labor; tosecure perfect lubrication, simply and cheaply, and to obtain otheradvantages and results as may be brought out in the following descrition.

Referrin .to the accompanying rawings, e numerals of reference indicatecorresponding parts in each oft-he several figures, Figure 1 is an endelevation, artly in section, of a shaft bearing rovided with dconstruction, said lubricator beingv an integral art of the cap of thebearin ;-Fig. 2 is a p an of-a ,lubricator constructe independently ofany bearingand adapted to be applied to a hearing at pleasure, no coverfor the reservoir and no cap for the wick-tube being shown, and Figs. 3and 4 are vertical sections taken on lines 3- 3 and 4-4, respectively,of Fig. 2 with said wick-tube cap. .In said drawin s, and articularlyFigs. 2, 3 and 4 thereo 10 in icates a reservoir adapted to containlubricant and which I have shown in the. drawings as cast in oneintegral piece, although obviously it could be put together in anysuitable and wellknown manner. Said reservoir 10 has projecting up fromits floor or bottom 11 a tube 12, the 'top of which is substantiallyflush with the t p offthe reservoir. A wick 13 is inserted; in the saidtube 12 and passed downward at the bottom. thereof through a hole 14 inthe bottom of the reservoir 10,

the end 15 of the wick below the said reservoir extending as desired tothe bearin which is to be lubricated, and the said'wic at the upper endof the tube 12 being bent or aperture 16 in t eir journals, such asaxles and the like,-

the wick 13, and regularity.

reservoir 10, (preferably extending to theand receives the wick 13easily,.so that the same can slide freely-therein, while above,

'the floor 11' the wick 13 is held central in the tube 12' b an annularpackin 18 of waste or the ii is and which is force ti htl into place asshown in the drawings. Fre erably a little cap 19 closes the top of thetube 12, and the one I have shown in the drawing comprises a disk20 witha hollow shank 21, or flange, adapted to project into the tube, saidshank or flange being slotted at one side, as at 22, to receive the wick13.

It will be understood that the reservoir 10 is to be mounted on top of abearing and the lower end 15 of the wick 13 extend to, or nearly to, thebearing surfaces. I have shown in the drawings a boss 23 upon the bottomof the reservoir around the wick. which facilitates the mounting of thedevice upon a bearing, although it is not absolutely necessary. Thereservoir being filled with oil nearly to the top of the tube 12 feedsthe same gradually to the bearing, through with great evenness and Thereis no waste of oil, and it is necessary'only to see that the reservoir10 is kept supplie F1 In Fig. 1, I have shown a.lubricator or myimproved construction applied to a bearing, and made an integralpart oi:the same, instead of separate. Here 25 mdicates the lower member of thebearing for the shaft 26 and 27 is the cap adapted to be secured by capscrews 28,. 28. My reservoir 29 is formed in the top of said cap and hasthe interior tube 30 with wick 31 arranged therein as previouslydescribed in connection'with the reservoir 10. The end 32 of said wickextendsdownward through a passage 33 in the cap 27 and its lining 35, ifthere be one, to close proximity to the shaft 26. A cover 34 is shownprovided for the reservoir 29, and obviously a cover Cclan always beused if desired to keep out irt.

Having thus described the invention, what I .claim is:

'1.- A lubricator comprising a reservoir having'an aperture in its wall,a tube in said reservoir of larger bore than said aperture imperviouslyconnected at one end to the wall of the reservoir around said aper tureand extending at its other end to the i ing a lateral recess or notch inthe edge 01, upper part of the reservoir, a wick extend saidlast-mentioned end,'a wick extending ing through said tube and aperturewith one through said aperture and tube and lateral end outside thereservoir and the other end recess or notch thereof with one end outside20 reaching to the lower part of the reservoir the reservoir and theother reaching to the chamber, said wick fitting the aperture and lowerpart of the reservoir chamber, said extending centrally through thetube, and an wick fitting the aperture and lateral recess annularpacking of waste or the like packed or notch and extending centrally ofthe tube, tightly around said wick in said tube. an annular packing ofwaste or the like 25 2.
